On the model
You want to extract some info via sql such as
select k.key_name, t.translation, t.date_finalization, l.code, l.description, tl.first_name, tl.last_name, tl.email
from translation t, language l, user tl, translation_key k
where
t.language_id = l.idlanguage
and tl.idUser = t.translator_id
and k.id = t.key_id
order by key_name
And you want to parametarize the extraction by passing some filtering input
select k.key_name, t.translation, t.date_finalization, l.code, l.description, tl.first_name, tl.last_name, tl.email
from translation t, language l, user tl, translation_key k
where
t.language_id = l.idlanguage
and tl.idUser = t.translator_id
and k.id = t.key_id
and k.key_name like ?
and l.code like ?
order by key_name
limit ?
And you want to have a REST access!
And you want it NOW!
Good news SDD Statement Driven Development is there for you!
From the above statement you can extract 3 info:
- an input (in java a DTO bean) with keyName, code, limit as params
- an output
(in java a DTO bean) with keyName, translation, dateFinalization, code, description, firstName, lastName, email
- a functionality to name
This is enough to get a REST-CXF application instantly!
This page will show you how to reach it!
Intro
This page correspond to a demo to belonging to a more global
presentation.
To be able to demostrate it there are couple of prerequisits:
- download minuteproject 0.8.1+
- install maven
- install tomcat
- install mysql and create the schema (see demo JPA2)
This page will show you how to:
- configure
- generate
- build
- deploy
- test
Configuration
Minuteproject works with a configuration file that indicates:
- where is the model
- how to enrich it
- enable Statement Driven Development declartion
- against which technologies to generate (targets)
Here is the configuration TRANXY-JPA2-Spring-REST-CXF-SDD.xml

Aside of the 'standard' CXF CRUD generation (see on
demo). Here a set of new artifacts are generated to enable the enriched 'get translation infos' function.
The part of the configuration may seem a bit long, I agree. It describes what templates and metadata file to use.
I plan to have simplify version à la minuteproject console where you just reference a track name belonging to a catalog and pass some properties.
The set of target currently displayed can be copied from the sample provided in
/demo/config.
Generation
Drop TRANXY-JPA2-Spring-REST-CXF-SDD.xml in /mywork/config and run: model-generation.cmd/sh TRANXY-JPA2-Spring-REST-CXF-SDD.xml
Generated artifacts go to
/DEV/latvianjug/tranxy.
Generated artifacts
Here are presented on the new artifacts of the CXF-JPA2 track.
The artifacts are presented from a top down perspective (starting from REST-Frontend down to Persistence layer).
The name of the artifacts are deeply linked to the query name 'get translation info'.
REST resources
2 resources file are generated, one for json rendering the other for xml.

Improvements
SDD concept is brand new inside minuteproject, a number of improvement are foreseen:
- error handling
- validation (type, mandatory)
- default value
Build deploy and test
Build
Run >mvn clean package from the root application
Deploy
Drop the resulting artefact tranxyRestCxfApp.war in tomcat/webapps
Start tomcat
Test
2 URLs - one for json format the other for xml format are available
REST URL with parameters returning json format
http://localhost:8080/tranxyRestCxfApp/rest/json/gettranslationinfos?key=%25&code=%25&max=2
Search for all key : % and all code : % and max number of return value is 2
REST URL with parameters returning xml format
Search for all key : % and all code : % and max number of return value is 1
Now you can enjoy and make cool front-end (ajax, jquery friendly and other js).
Conclusion
If you want to go fast, and when working with ORM abstraction takes to long, then have a look at
Statement Driven Development.
The war between pro Domain Object vs. DTO is irrelevant for Minuteproject.
On this project both live aside.
Use the approach that best suits your needs.
